I just bought a diamond online and will be taking it to an independent diamond appraiser to get their take on the diamond. I have never done this before. Can anyone please give me an idea of what I should expect from a visit to the appraiser? Areand ASET images and Sarin tests common place or is that typically extra? Also, how much would the appraisal typically cost for something 2.7ct? Thanks, any information would be very helpful so I can start calling around ASAP. I wish I could use the PS approved appraisers, but there aren''t any in my area.
